Here’s a TEP-PO-KORAK A guide about you to get a waiting for a waiting in a metamascus using a web3-react:
1. Set your Metamascus Barallet and Web3-React library
First, you need to set up a metamascus wallet and install the web3-react library.
`Bash
Installed NPX metamask
NPM Install a web3 reaction
`
2. The import of the necessary libraries in your code
In your JavaScript file, import the necessary libraries.
Javascript
Import web3 from 'web3-react';
Metamskprovider import.
3. Initialize the Metamascus provider and get a user's Eddress
Make an instancemetamaskroviderand use it to get your current user.
Javascript
Const Provider = new metamaskprovider ();
Const Usraddress = Dar.getaddress ();
4. Create an instance of web3 with a Metamascus service provider
Now create a new instanceweb3using yours.
Javascript
Const Web3 = New Web3 (Provider);
5. Use The METTERTRANSACTIONCOUNT to get a transaction waiting.
Use an instance method of Web3 'Instance Web3to get the Pening number number
Javascript
async function yourtpendingtransactions () {{{
Const
return txcounts;
Iche
// Call the function
Getpndingtransactions (). then (txcounts) => console.log (txcounts));
Examples of cases of use
Here's how you can work to deal with errors and display transactions in more convenient.
Javascript
Import web3 from 'web3-react';
Metamskprovider import.
Const Provider = new metamaskprovider ();
Const Web3 = New Web3 (Provider);
async function yourtpendingtransactions () {{{
Triy {
Const
return txcounts;
} capture (error) {
Console.error (error);
Return 0; // Return 0 if there are no waiting transactions
Iche
Iche
// Call the function
Getpndingtransactions (). then (txcounts) => console.log (txcounts));
How to deal with errors and marginal cases
When you use'e_getraTransationCount ", you can supply an error or limit problems. Here's how you can change the solution code:
Javascript
async function yourtpendingtransactions () {{{
Const
// Check county error transaction
If (txcounts <1) {// if no waiting transaction, return 0
Console.error ('No Transaction');
Return 0;
Iche
return txcounts;
Iche
// Call the function
Getpndingtransactions (). then (txcounts) => console.log (txcounts));
This code will record an error if there is no pending transaction and instead show "0".
Conclusion
To get a waiting for a waiting in a metamascus use of web3-react, you can monitor TheES:
- Initialize the wallet of your metamic and theweb3-react
library.
- Get your current user andmetamaskrovider
.
- Make a new instanceweb3
using your.
- Use the method_ettransationCount to achieve a transaction to gluing.
Remember to treat mistakes, marginal cases and potential Aresuits limits working on a WTH web3 reaction in your applications.
